WASHINGTON D.C. -- Donald Trump's tax plan is out.

“It will provide major tax relief for middle income and for most other Americans. There will be a major tax reduction,” he says.

He says under his plan there will be a "zero rate" for low income Americans—folks making less than 25K and couples below 50K would pay no federal taxes. Trump also says he wants to cut corporate taxes and raise the bill on wealthy Americans.

Trump continues to lead in the polls, with Ben Carson by his side. The latest NBC/Wall Street Journal poll shows the duo neck and neck with 21 and 20 percent respectively, followed by Carly Fiorina and Marco Rubio, tied with 11 percent a piece.

On the other side of the aisle, Hillary Clinton told NBC News over the weekend that she is trying to be as forthcoming as possible when it comes to issues surrounding her private email server.

"What I've tried to do in explaining this is to try to provide more transparency and more information than anybody that I'm aware of who has ever served in the government and I'm happy to do that. Because I want these questions to be answered," she said.

But a recent Fox News poll says 58 percent of voters think she's not telling the truth. We will see if the topic comes up at the democratic debate in two weeks. Clinton will be on the CNN stage alongside Bernie Sanders, Martin O’Malley, Jim Webb, and Lincoln Chafee and possibly Joe Biden.

The vice president hasn't said he's running, but CNN's revised criteria makes it possible for him to hop into the race that day and still be on stage that night.
